Java Scanner - nextShort() Method

The java.util.Scanner.nextShort() method is used to scan the next token of the input as a short. This method will throw InputMismatchException if the next token cannot be translated into a valid short value as described below. If the translation is successful, the scanner advances past the input that matched.

Syntax

public short nextShort(int radix)

Parameters

Return Value

Returns the short scanned from the input.

Exception

• Throws InputMismatchException, if the next token does not match the Short regular expression, or is out of range.
• Throws NoSuchElementException, if input is exhausted.
• Throws IllegalStateException, if this scanner is closed.

Example:

In the example below, the java.util.Scanner.nextShort() method is used to scan the next token of the input as a short.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {

    //String to scan
    String MyString = "Hello World 10 + 20 = 30.0";

    //creating a Scanner
    Scanner MyScan = new Scanner(MyString);

    while(MyScan.hasNext()) {
      //if the next is a short
      //print the short with radix 16
      if(MyScan.hasNextShort(16))
        System.out.println("Short value is: "+ MyScan.nextShort(16));
      //if the next is not a short
      else
        System.out.println("No Short Value found: "+ MyScan.next());
    }

    //close the scanner
    MyScan.close();
  }
}

The output of the above code will be:

No Short Value found: Hello
No Short Value found: World
Short value is: 16
No Short Value found: +
Short value is: 32
No Short Value found: =
No Short Value found: 30.0
